Hi there,
i'm a big fan of cnc machines, i've build 2 till today... 1 was on wood structure which was a total headache and an aluminum frame based one, which is nicer and heavier
i used only stepper motors until now, so i am new to servo motors.... so before i start anything i want to ask a few things
which are the best solutions to replace my 3 and 4 nm stepper morots and drives. Has anyone bought used servo kit (motor+drive) from ebay?
I have a servo motor around here, it's SIEMENS 1FK7040-5AK71 (1nm torque) and on internet i found that is part of Siemens Sinamics 120 family
It's new, weights 4kgs and it looks very nice, but here are the questions:
1. what driver / amplifier can i use? beside sinamics family which is extremly expensive...
2. signal plug looks like an rj45 connector, where do i find pinouts?

thanks a lot!
